For Clarity and because I left a line in that I meant to delete:
Mining and Processing costs: = $24.27 per tonne (using 3:1 Strip ratio - 3tonnes Mined = 1 tonne Ore)
Number of tons: = 30 mt * 1.24% = 372,000 tonne of Copper (using their CuEq Calc, which is out of date but acceptible for long term prices perhaps)
Revenue: @ say $AUS6,600 per tonne = $2,455,000,000 or $2.455 Billion ($A3 per lb - this is quite high for most long term planning - particularly the way the Aussie dollar is going)
Costs 1: Mining and Processing @ $24.27 per tonne = $728,100,000
Costs 2: Admin/exloration @ say $10 mill per year = $100,000,000
Costs 3. Financing/Infrastructure/Transport = $500,000,000 (You have to finance the mill somehow - you can do it with equity if you like - I think the EPS would not change much)
